FIGURE 1 in Natural history and distribution of the enigmatic southern Appalachian opilionid, Fumontana deprehendor Shear (Laniatores: Triaenonychidae), with an assessment of morphological variation
FIGURE 1. Distribution of sampled Fumontana deprehendor in the southern Appalachian mountains. A total of 24 localities were sampled, including both previously published localities (Shear 1977, 1978), labeled here as GREENBR and JOYCE. Dark circles represent sampled localities, with the size of circles proportional to the number of specimens collected. Open circles represent unsuccessful collecting attempts. Dark lines represent the four regions of "predicted endemism" (defined in the text) used as grouping variables in morphological analyses. These areas are regional highlands separated by major lowland riverine barriers. Stippled areas indicate elevations above 1000 meters.
FIGURE 2 in DNA sequences and morphological variation in Lophiodes iwamotoi Ho, Serét & Shao, 2011 based on new material from New Caledonia
FIGURE 2. Polymorphic nucleotide sites at the cytochrome c oxidase subunit-I locus (A) and Rhodopsin locus (B) in two Lophiodes species collected from seamounts off New Caledonia. Diagnostic nucleotides of L. iwamotoi to L. mutilus are highlighted. Numeration of nucleotide sites starts from first nucleotide of the corresponding genes. The sequences used for the examination were deposited in NCBI Genbank. Their accession numbers are given.

Figure 2 in Reassessment of molecular and morphological variation within the Anagrus atomus species complex (Hymenoptera: Mymaridae): egg parasitoids of leafhoppers (Hemiptera: Cicadellidae) in Europe and North America
Figure 2. Inter- and intragenomic relationships among the ITS2 rRNA sequences of 56 Anagrus 'atomus' complex specimens. The analysis involved 29 direct-sequenced specimens and 69 cloned sequences from a further 27 specimens. Circular mid-point rooted neighbour-joining tree inferred from pairwise uncorrected p-distances calculated in MEGA v.6.06. Branch support>50% (assessed with 1000 bootstrap replicates) is shown next to the branches. Intragenomic variation in the placement of just three individuals morphologically identified respectively as A. atomus, A. erythroneurae, and A. parvus are highlighted with dashed lines (3 cloned sequences for each specimen). Two morphologically unresolved specimens are further highlighted in bold. PR numbers relate to GenBank accessions MW012950–MW013047.
